Really nice! I like the Minecraft-zombie-meets-tortoise-looking creatures!
is it me or are the shadows a little inconsistent? The tower casts a shadow to the right, but the waterfall seems to cast a shadow to the left. Either way, another banger for sure. I might actually play mineycrafta if it looked like this
Nice! 
How have you found the tile mapping in the beta? I guess you tiled "cubes" (front and top face of each block) rather than squares (top face)? I like the modulated light, it gives the impression there's some of-screen volumes creating shade!
Very nice.
PERFECTION!
